Never see any x68000/FM Towns emulator ported to dingoo. I know the existance of two emulators for the x68000, one for windows (XM6) and one working on linux (Virtual68k). The source codes of these emulators can be found here:http://boards.openpandora.org/index.php?/topic/961-xm6-source-code/
As for the FM Towns Marty i think the only good emulator is the UNZ for windows. Is there any chance to see one day emulators of those two systems on dingoo native/dingux? Anyone working on them?
